Technodiversity Glossary

Picking up logs that are stored alongside skid road, normally separating different assortments, forwarding them to forest road, unloading. 

 

Functiogram

Advantages

• High performance
• Perfect combination with harvester 

Limitations, thresholds

• Trafficability of forest ground:
  • several passes
  • high ground pressure
  • velocity and starting/slowing down in high frequency

Main use

• Standard on trafficable stand and ground

Economic suitability

Example:

• machine costs without personal costs: 90,00 Euro/h
• personal costs per person: 35,00 Euro/h
• number of persons: 1
• in total: 125,00 Euro/h
• regression line minutes per tree
  • b₀ (loading, unloading) = 0,0
  • b₁ (tree volume) = 4,0
  • b₂ (skidding distance) = 0,003

Ecological suitability

Social suitability:

• S-class: unloading short logs on the road -> S4
• E-class: advanced machine work, moderate -> E4
